What Causes Tooth Sensitivity And How To Fix It

Tooth sensitivity is a common oral health issue that affects millions of people around the world. It is characterized by sudden, sharp pains or discomfort in the teeth, usually triggered by hot or cold temperatures, sweet or sour tastes, or pressure. While tooth sensitivity can be a minor annoyance for some, for others, it can be a significant source of discomfort and pain. But what causes tooth sensitivity, and more importantly, how can it be fixed?

Causes of Tooth Sensitivity

Tooth sensitivity is often caused by the exposure of the dentin, a layer of tissue beneath the enamel, to hot or cold temperatures. This exposure can occur due to a variety of factors, including:

1. Worn Enamel: Over the years, the enamel on the teeth can wear down, exposing the dentin below. This can be caused by factors such as teeth grinding or clenching, genetic predisposition, or using abrasive toothpaste.
2. Gum Recession: When the gums recede, the roots of the teeth are exposed, leading to sensitivity.
3. Cracks in the Teeth: Small cracks in the teeth can allow hot or cold substances to reach the inner layers of the tooth, causing sensitivity.
4. Dental Work: Fillings, crowns, or other dental work can also cause tooth sensitivity if they are not properly placed or if there is a gap between the restoration and the tooth.
5. Acid Erosion: Acidic foods and drinks can erode the enamel, exposing the dentin and leading to sensitivity.
6. Dentin Hypersensitivity: A condition where the dentin becomes inflamed, causing sensitivity.

How to Fix Tooth Sensitivity

Fortunately, tooth sensitivity can be managed and treated. Here are some methods to fix tooth sensitivity:

1. Desensitizing Toothpaste: Using a desensitizing toothpaste that contains potassium nitrate or strontium chloride can help block the dentin tubules and reduce sensitivity.



2. Fluoride Toothpaste: Fluoride toothpaste can help repair and strengthen tooth enamel, reducing sensitivity.
3. Professional Treatments: Your dentist can apply a desensitizing agent to the affected tooth or teeth, or perform a procedure to remove dentin tubules.
4. Root Canal Treatment: In cases of severe tooth sensitivity, a root canal treatment may be necessary to remove the infected pulp and reduce sensitivity.
5. Chewing Gum: Chewing sugar-free gum that contains xylitol can stimulate saliva production, which can help neutralize acid and reduce sensitivity.
6. Avoid Triggering Foods and Drinks: Avoiding acidic, sugary, or hot/cold beverages can help reduce sensitivity.



7. Maintain Good Oral Hygiene: Regular brushing and flossing can help prevent tooth sensitivity by removing plaque and tartar buildup.

In conclusion, tooth sensitivity is a common oral health issue that can be caused by a variety of factors. By understanding the causes of tooth sensitivity and using the right techniques and products, it is possible to manage and fix tooth sensitivity. If you are experiencing tooth sensitivity, it is important to consult with your dentist to determine the best course of treatment for your specific case. With proper care and attention, tooth sensitivity can be alleviated, allowing you to enjoy good oral health and a bright, confident smile.
